Honda is to introduce the world’s first predictive
cruise control system known as Intelligent Adaptive Cruise Control
(i-ACC), capable of foreseeing and automatically reacting to other
vehicles ‘cutting-in’ to the equipped vehicle’s lane.
Based on extensive real-world research of typical
European driving styles, Honda’s Intelligent Adaptive Cruise Control
(i-ACC) uses a camera and radar to sense the position of other vehicles
on the road. It then applies an algorithm to predict the likelihood of
vehicles in neighbouring lanes cutting-in by evaluating relations
between multiple vehicles, enabling the equipped vehicle to react
quickly, safely and comfortably.
i-ACC will make its debut this year on the new
European CR-V*, building upon the traditional Adaptive Cruise Control
(ACC) system. Traditional ACC systems keep a preselected longitudinal
velocity, which is only reduced for maintaining a safe distance to a car
in front. However, if a vehicle cuts-in from a neighboring lane, the
traditional ACC system reacts later thus requiring stronger braking.
The new i-ACC system is able to compute the
likelihood of a cut-in up to five seconds before it occurs, and is
therefore designed to react very smoothly so as not to startle the
driver, who might not yet be aware of the imminent cut-in. In this case
the system applies just a mild brake initially, with an icon appearing
on the driver display , informing the driver why a slow-down occurs.. It
then proceeds to apply a stronger brake to adapt the velocity to keep a
safe distance. Dr. Kleinehagenbrock, responsible for i-ACC at Honda
R&D Europe (Deutschland) GmbH says, ‘i-ACC takes cruise control
systems to a whole new level, offering what we call ‘predictive safety’.
i-ACC recognises the side of the road you are
driving on whether in the UK or on the continent and automatically
detects which neighbouring vehicle is the most critical to be aware of
at any given moment.
i-ACC is the result of an in-house Research &
Development project undertaken by an international Honda team in Europe
and Japan, specifically designed for European roads. Research into
driver behaviour to develop the algorithm was carried out across Europe.
Dr. Schmuedderich, responsible for i-ACC at Honda
Research Institute Europe GmbH comments: “i-ACC is a significant
breakthrough and a considerable further step towards a new generation of
driver assistance systems that anticipate the behavior of other traffic
participants.”
*i-ACC will be available on the 2015 European CR-V, Executive grade only.
